EcoFlow DELTA Pro + Smart Extra Battery + 400W Solar Panel

This is the complete package: a DELTA Pro, a Smart Extra Battery that doubles it to 7200Wh, and a 400W portable solar panel to refill it without a wall outlet. Bought together it covers all three things a backup system needs — enough storage to matter, enough output to run real appliances, and a way to recharge when the grid is the thing that's failed.

7200Wh at 3600W continuous will carry a refrigerator, a furnace fan, lighting and your devices through a long outage, and the 400W panel means a multi-day outage doesn't end with a dead battery. Renewable Outdoors is an authorized EcoFlow dealer — call us at (303) 876-7654 and we'll sanity-check the setup against what you actually want to keep running.

Why This Bundle

7200Wh Combined

The DELTA Pro plus one Smart Extra Battery — double the runtime of a DELTA Pro on its own, with room for one more battery later.

3600W Continuous, 7200W Surge

Full-size appliances rather than just electronics, with X-Boost handling resistive loads up to 4500W.

400W Solar Panel Included

Enough panel to recover a meaningful amount of energy each day — the difference between a backup that runs down and one that keeps going.

1.8-Hour AC Recharge

MultiCharge combines AC and solar for up to 6500W of input when you need to refill in a hurry.

Plug-and-Play Assembly

The extra battery connects with one cable and the panel with one connector. No installer, no rewiring.

LFP Cells, 3,500 Cycles to 80%

Lithium iron phosphate throughout — roughly a decade of daily cycling, and safe to keep indoors.

EcoFlow DELTA Pro + Smart Extra Battery + 400W Solar Panel: Frequently Asked Questions

What exactly comes in this bundle?
A DELTA Pro power station, one DELTA Pro Smart Extra Battery, and a 400W portable solar panel, along with the charging cables and the battery connection cable. It's the three-part system rather than three separate purchases to assemble yourself.
How long will 7200Wh run my essentials?
Divide 7200 by your draw in watts. A fridge, LED lighting and devices at around 250W gives you roughly 28 hours. Add a furnace fan and you're looking at 11 or 12. The 400W panel then adds energy back each day on top of that. Call us at (303) 876-7654 with your list and we'll work through it properly.
How much will the 400W panel actually put back in a day?
In good conditions, expect somewhere around 1.5 to 2kWh over a day of useful sun — real-world output is always below the rated wattage because panels are rated under standard test conditions. That's a meaningful fraction of your storage recovered daily, which is what turns a backup into something you can live on.
Can I add more solar or another battery later?
Yes to both. The DELTA Pro accepts up to 1600W of solar, so there's a lot of headroom above the 400W included here. And it supports a second Smart Extra Battery, which would take you to 10,800Wh. Both are plug-in additions.
Will it run a 240V well pump?
Not by itself — a single DELTA Pro is 120V. Two DELTA Pros joined by the EcoFlow Double Voltage Hub produce 240V and up to 7200W. If a well pump is the reason you're buying, call us first and we'll check its starting surge against that figure.
Is it safe to run indoors?
Yes. There's no fuel and no exhaust, which is precisely why battery backup has largely replaced small gas generators for indoor use. The LFP cells are the most thermally stable of the common lithium chemistries, and the BMS monitors the pack continuously. Keep it dry with airflow around the vents.
Can I use it as a UPS?
Yes. It passes wall power through and switches to battery when the grid drops, fast enough for computers, networking gear and most home electronics. For medical equipment, verify the switchover tolerance with the device manufacturer first.
How heavy is all this?
The DELTA Pro is about 99 lbs and the extra battery about 84 lbs, both with handles and designed to be positioned once rather than carried regularly. The solar panel folds into a carry case and is a one-person job. Plan for two people when you first set the units in place.
What warranty do I get?
Five years on the DELTA Pro and the extra battery. The foldable solar panel carries a 3-year warranty. We're an authorized EcoFlow dealer, so all of it goes through EcoFlow's normal warranty process with our support behind it.
Do you offer financing or price matching?
Yes. We offer 0% APR financing options through Affirm at checkout, and our Lowest Price Guarantee applies — if you find this bundle cheaper at another authorized dealer, call us at (303) 876-7654 before you order and we'll take care of it.
